Our Product : SPEX-A firmly

Summary of Our Product

SPEX-A firmly controls the elution of heavy metal in the soil or waste water capturing during mineralization of the material and tightly bonded in to the mineral.
The insolubilization is performed in neutral to alkali environment; pH control is necessary under acid environment.

Lineup

SPEX-A can control the elution of arsenic, fluorine, boron, lead and cadmium.
The range of use may be widened by changing the type of SPEX-A, depending on the condition, characteristics (soil, waste water, pH etc) and concentration of the contamination.

Basic Performance of Adsorption Ability

SPEX-AP Relation between Dosage and Heavy Metal Density

Test Method
For the density target of 5mg/L(ppm) of the simulated waste water (100ml), SPEX-A is added at amount of 0.1g,0.2g,0.3g,0.5g and1g. Shaken for six hours, after a centrifugation, the supermatant is collected for evaluation.
The simulated water is in neutrality; pH is adjusted to 9 ~ 10 with pH regulator agent.
